Installation structure of brake pedal

Abstract

An installation structure releases a brake pedal in a vehicle collision. A pedal arm has a groove coupled with a pipe. A front portion of the groove has a smaller width than the pipe. Alternatively, a pedal arm is hingedly mounted on a support member. A connector secures the pedal arm to the support member for normal operation, and permits separation of the pedal arm from the support member in response to a reward force resulting from a collision impact. The support member has a cylindrical member, and the pedal arm defines a forward facing opening, force-fit onto the cylindrical member. The opening has a width smaller than the cylindrical member. Alternatively, the connector has two support plates on a pipe of the cylindrical member, at both sides of the pedal arm. The plates have rear-facing grooves, and coupling members protruding from the pedal arm are received in the grooves.

1. An installation structure of a brake pedal, the structure comprising:
 a hinge pipe; 
 a pedal arm formed with a hinge groove, wherein said hinge groove is coupled to said hinge pipe, and a portion of said hinge groove opening toward a frontal direction of a vehicle has a smaller width than that of the outer diameter of said hinge pipe; 
 two supporting plates equipped on said hinge pipe disposed at both sides of said pedal arm and having a plurality of coupling grooves opening towards a rear direction of the vehicle; and 
 coupling members inserted into said coupling grooves and fixed to said pedal arm. 
 
   
   
     2. The structure as defined in  claim 1 , wherein said coupling members are configured to have heads for closely adhering to lateral sides of said supporting plates. 
   
   
     3. A brake pedal structure, comprising:
 a support member comprising a cylindrical member having a diameter and comprising a hinge pipe; 
 a brake pedal arm having a pedal at one end and being hingedly mounted on the support member at an opposite end, said brake pedal arm defining a forward facing opening at said opposite end, said opening being configured and dimensioned to be force-fit onto said cylindrical member; and 
 connection means cooperating between the support member and pedal arm to secure the pedal arm for normal operation and to permit separation of the pedal arm from the support member in response to a reward force resulting from a collision impact, wherein said connection means comprises two support plates mounted on the hinge pipe at both sides of the pedal arm, said plates having a plurality of coupling grooves opening towards a rear direction, and coupling members protruding from said pedal arm received in said coupling grooves. 
 
   
   
     4. The brake pedal structure of  claim 3 , wherein said opening has a width smaller than said cylindrical member diameter.
